Description
While lasem parses entity named in body text correctly, it doesn't in attribute strings.
For exapmle, the mathml below is rendered correctly,
<mo>
⌊</mo>``<mo>
⌋</mo>
however, the one blow isn't. A warning is shown as : Pango-WARNING **: Invalid UTF-8 string passed to pango_layout_set_text()
</mfenced>
The one below works.
</mfenced>
